Specification of Letters Patent.

Pate-mama 29, 191 '7.

Application filed January 4, 1916. SeriaINo. 70,253.

To all whom it may concern:

Be it known that LIERNns'r LISELL, a citizen of the United States, residing at Dalbo, in the county of Isanti and State of Minnesota, have invented certain new and useful Improvements in Stovepipe-Cleaners, of which the'following is a specification.

My invention relates to stove pipe cleaners.

The primary object thereof resides in the provision of a device of this character that is adapted for removing soot or other dirt from the interior of a stove pipe in a 0011- venient and efficient manner.

Another object of this invention resides in the provision of a bar with which is adjustably associated a cleaning means adapted for association with various sized pipes which is rotatable through the medium of novel supporting and guiding means for the bar.

A further object of this invention resides in the provision of novel means for efliciently changing the rectilinear movement into an alternate rotary movement ,to consequently cause the cleaning means onthe bar to rotate simultaneously with the actuation of the novel operating means.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction, efl'icient in operation and one that can be manufactured and placed on the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawingsand pointed out in the claim forming a part of this specification.

In the drawings Figure 1 is a side elevational view of my invention arranged within a stove pipe in a longitudinal section;

Fig. 2 is an enlarged rear elevational view of the brush supporting plate;

Fig. 3 is an enlarged front elevational View of the operating means; and a Fig. 4 is an enlarged fragmentary detail showing the connection between the supporting arm and the brush supporting plate.

Referring more particularly to the drawings in which similar reference characters designate like or corresponding 4 parts throughout the various views, I provide a supporting bar 1 formed of any desirable metal which isrelatively flat in cross section and also twisted throughout its length into plate 3 the vertices of which are bent at right angles to provide a flange --4 in which is formed an opening. The plate is further provided with radiating slots 5, one slot of which extends toward each vertex. A plu- .rality of brush bodies 6 have bristles 7 extending therefrom and arms 8 extending from the sides opposite the bristles. These arms extend through the openings in the flanges and have their angular bent ends 9 engaged by washers 10,slidably adjustably arranged within the slots 5 and finally engaged at their free threaded terminals by nuts 11. It is readily apparent that the nuts and washers cooperate to removably hold the angularly bent ends 9 in various adjusted positions in the slots 5 to consequently regulate the distance between the flanges and the brush bodies so that the cleaning means can be adjusted to conform to the diameter of various sized pipes. Connection is preferably maintained through the medium of semi-circular clamps 12 which are connected to the end of the body 4 through the medium of a suitable fastening device preferably a rivet 13 said clamps first engaging a ball 14 from which projects astem 15. This stem has a collar 16 formed on the outer end thereof which abuts the plate 3 when the free threaded ends of the screw pass through the central opening in the plate. A nut or likeadjusting element 17 serves to hold-the plate in position. I

Connected to the opposite end of the bar 1 through the medium of suitable fastening means preferably rivets 18 is a bifurcated end 19 of a stub shaft 20. A collar 21 is formed on the inner end of the shaft while the sleeved end 22 on the handle 23 is rotatably mounted on the shaft, the inner end of the sleeve bearing against the collar 21 and nut or like adjusting-device 24 maintaining the handle in position.

For the purpose of imparting a rotary movement to the cleaning means I have associated my supporting and guiding means with the bar 1 preparatory to the application of either a cleaning means or the ating means consists of a disk 25 which has an oblong slot 26 therein and twisted rectangular guides 27 project from opposite sides of the disk 25 adjacent the slot 26. Studs 28 project from opposite points on the periphery of the disk 26 and are rotatably mounted in the free ends of a yoke 29. Depending intermediate the ends of the yoke is a rod 30 maintained in engagement with the yoke through the medium of a nut 31. An angular collar 32 cooperates with the nut in maintaining the rod in substantially rigid relation with the yoke while a sleeve handle 33 is rotatably mounted about the rod. Another annular collar 34: is associated with the free re duced end of the rod and is maintained thereon through the medium of a nut or like fastening device 35. It will now be apparent that when the handle 23 is held in one hand and when the sleeve handle 33 is held in the other by exerting a reciprocatory movement to the bar because of the arrangement of the rectangular twisted guides which cooperate with the twisted bar the rectilinear movement will impart a rotary movement to the bar and consequently alternately rotating the cleaning means. stud 36 extends through the bar adjacent the end to which the handle is connected and serves as a stop for limiting the movement of the bar through the guiding and supporting means.

The operation of my invention is as follows Assuming that the nuts 11 have been adjusted so that the brushes are arranged in their proper position so that they will be arranged in close relation with the interior diameter of the pipe to be cleaned, the handle 33 is engaged and the brushes placed within the pipe. The supporting means or handle 33 is now held adjacent the edge of the pipe to be cleaned and by moving the bar and cleaning means within the interior of the pipe through the medium of the operating handle 23, because of the twisted guides 2 as the handle 23 is moved backwardand forward the brushes will be consequently rotated and will remove soot and other dirt from the interior of the pipe.

Copies of this patent may be obtained for Although I have shown and described the preferred embodiment of my invention I desire it to be understood that I am not to be limited to the exact details shown, however, I desire that great stress be laid upon the arrangement of the handle cooperating bar and supporting and guiding means for changing the rectilinear movement into alternating rotary movement. Attention is also directed to the rotatable adjustable cleaning means carried by the bar.

From the above description taken in connection with the accompanying drawings, it can easily be seen that I have provided a device that is simple in construction, containing but a few simple parts that can be cheaply manufactured and assembled and when assembled can be placed upon the market and sold at a minimum cost.

It will be understood that the above description and accompanying drawings comprehend only the general embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of the parts may be made within the scope of the appended claim and without sacrificing any of the advantages of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

A stove pipe cleaner including a triangular plate provided with slots radiating from the center and extending toward the vertices thereof, supporting flanges formed at the vertices, a plurality of brushes, arms extending from the brushes and slidably supported in the flanges, the inner arms being bent and arranged through the slots, nuts threaded upon the extremities of the bent ends of the arms for removably holding the arms in various adjusted positions on the plate to consequently hold the brushes in an adjusted position, and means for operating the plate.

In testimony whereof I affix my signature in presence of two witnesses.
